Abstract
The utility model provides a center distance measuring specimen column of a cylinder roller bearing cage pocket. The following technical measures are specifically adopted to solve the technical problem of the existing measuring specimen column: the measuring specimen column comprises a cone (1), a butterfly nut (2), an open washer (3) and an open taper sleeve (4), wherein the cone (1) is placed in the open taper sleeve (4); the open washer (3) is sheathed on the cone (1); and the butterfly nut (2) on the open washer (3) is screwed on the cone (1) to assemble one measuring specimen column. Two measuring specimen columns are respectively put in two corresponding pockets (5) for measurement and calculation. The center distance measuring specimen column is characterized by accuracy in measuring the center distance of the pockets, in particular deep pockets. The measuring specimen column effectively reduces measurement error and ensures processing accuracy. The cone, the open washer and the tapered sleeve are convenient to disassemble. The butterfly nut is available for general use.
Description
Technical field
The utility model relates to the retainer survey instrument, is specifically related to a kind of cylinder roller bearing retainer pocket hole center distance measurement sample post (be called for short and measure the sample post, down together).
Background technology
Existing cylinder roller bearing retainer center distance measurement sample post (is called for short the existing sample post of measuring, be the cylinder solid down together), because there is the phenomenon of expanding with heat and contract with cold in actual processing retainer, the pocket bore dia is greater than the size of sample post, and the sample post is a fixed value, therefore the sample post is put into the pocket hole exists certain clearance, behind the application of sample post, and the upper and lower numerical value difference that records of pocket hole centre distance.See accompanying drawing 1.
Summary of the invention
The utility model provides a kind of cylinder roller bearing retainer pocket hole center distance measurement sample post.
Specifically take following technical scheme for solving the problems of the technologies described above: measure the sample post and constitute by cone (1), wing nut (2), open washer (3) and opening tapered sleeve (4); Described cone (1) is placed in the opening tapered sleeve (4); Described open washer (3) is enclosed within on the cone (1), and described wing nut (2) is being screwed on the cone (1) on the open washer (3).
The external diameter of described open washer (3) is greater than the opening diameter of opening tapered sleeve (4).
The utlity model has and measure pocket hole centre distance characteristic of accurate, especially darker pocket hole is more obvious, measures the sample post and effectively reduces measuring error, has guaranteed the precision of processing; Cone, open washer and taper sheath convenient disassembly; Wing nut can be general.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the existing sample post instrumentation plan of measuring;
Fig. 2 measures sample rod structure figure;
Fig. 3 measures sample post instrumentation plan.
Wherein: cone 1, wing nut 2, open washer 3, opening tapered sleeve 4, pocket hole 5, center distance measurement point 6.
Embodiment
As shown in Figure 2, measure the sample rod structure and comprise cone 1, wing nut 2, open washer 3 and opening tapered sleeve 4; The under shed of cone 1 by opening tapered sleeve 4 upwards is placed in the opening tapered sleeve 4, and open washer 3 is enclosed within on the cone 1, and the external diameter of open washer 3 should be greater than the upper shed diameter of opening tapered sleeve 4; Wing nut 2 is assembled into one and measures the sample post being screwed on the open washer 3 on the cone 1.For the different pocket hole 5 of diameter, should use vary in size, corresponding opening tapered sleeve 4 and open washer 3, and can be with onesize wing nut.
As shown in Figure 3, use and measure in the sample post measuring process, at first install and measure the sample post, earlier two opening tapered sleeves 4 and cone 1 are put into corresponding two pocket holes 5 respectively, again open washer 3 is inserted in square thread place on the cone 1, at last wing nut 2 is screwed on the cone 1, by progressively tightening wing nut 2, cone 1 is moved on progressively, with opening tapered sleeve 4 swelling pocket holes 5; Measure then, the outer side center that slide calliper rule is stuck in taper sheath 4 can be measured retainer pocket hole centre distance apart from measurement point 6 places.When pocket hole five equilibrium is odd number: the centre distance of surveying out=drawing centre distance * cos (90/ five equilibrium)+pocket bore dia; When pocket hole five equilibrium is even number: the centre distance of surveying out=drawing centre distance+pocket bore dia.
Through the analysis to cylinder roller bearing retainer pocket hole center distance measurement error, the measurement sample post after the improvement structure reduces measuring error effectively, has guaranteed the precision of processing.
Claims (2)
1. cylinder roller bearing retainer pocket hole center distance measurement sample post is characterized in that: described measurement sample post is made of cone (1), wing nut (2), open washer (3) and opening tapered sleeve (4); Described cone (1) is placed in the opening tapered sleeve (4); Described open washer (3) is enclosed within on the cone (1), and described wing nut (2) is being screwed on the cone (1) on the open washer (3).
2. according to the described a kind of cylinder roller bearing retainer pocket of claim 1 hole center distance measurement sample post, it is characterized in that: the external diameter of described open washer (3) is greater than the opening diameter of opening tapered sleeve (4).
